The introduction of modern high-pressure diesel injection systems has led to an increase in the demands on workshops.
Absolute cleanliness is a requirement for installing and removing components, and during testing and repairs. We need to ensure a ‘dust-free’ working environment for high pressure diesel fuel injection component repair.
Bosch PH asked us to set up a Cleanroom in Malabon Diesel for CRI/CRIN/UI/UP repair. We said yes.
Like those found in semiconductor and pharmaceutical manufacturing facilities, we commissioned a cleanroom contractor to build one.
How good is it?
It can filter particles as small as 1 micrometer. For reference, a hair strand is usually 80 micormeters in diameter.
Scrub suits are required to maintain cleanliness.
Commonrail injector assembly is done inside the cleanroom. "Third-stage" automatic measurement equipment ensure that standards are exactly met.
ISO 14644‐1 cleanroom standards
We now have a class 400 at 1 micrometer particle size clean room (Room classification between class 1,000 and class 10,000).
Does it really meet Bosch cleanroom standards?
How the cleanroom is tested:
- Air Velocity
- Filter Integrity test using Emery 3004 Challenge
- 3-point Particle Test
- 1-point Temperature and Relative Humidity Test
- 1-point Room Pressure Test
It is the first and only cleanroom in the PH diesel repair industry. And we are very happy that we built one for you.
